Product Description

The M4x16 hex bolts are precision-engineered metric fasteners designed for robust mechanical connections in industrial applications. These external hex bolts M4x16 feature a 4 mm nominal diameter with a 16 mm shank length, complying with ISO 4014/DIN 931 standards. Manufactured from carbon steel or stainless steel (Grade A2/A4), they offer tensile strengths up to 8.8 grade (carbon) or 70 MPa (stainless). The external hex head requires a 7 mm wrench for installation, suitable for torque values up to 5.6 Nm. Surface treatments include zinc plating for corrosion resistance (-50°C to +150°C operational range). Commonly used in machinery assembly, automotive components, and electronic enclosures, these metric hex screws M4x16 provide secure fastening but require sufficient workspace for wrench access. Compatible with ISO 4032 nuts and standard washers.
